1 Claim.

This invention relates to sliding sash, particularly for vehicles, as buses, and has for its object a weather strip construction, which is free of moisture absorbent material, so that it remains the same under all weather conditions, as it is not affected by moisture, and hence is easily and uniformly operable under all conditions, and further holds the sash from developing looseness and rattling.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is an isometric view of this window construction, the contiguous portion of the vehicle body being also shown.

Figure 2 is an enlarged sectional view on line 2-2, Figure 1. i

Figure 3 is a fragmentary edge view of the sash.

l designates the window frame suitably mounted in a window opening of a car body 2, the frame being formed with an inwardly facing sash guide or sash receiving channel. The frame may be of any suitable construction to provide an inwardly extending guide flange 3 which, in the illustrated embodiment of the invention, forms one side of the sash guide channel 4.

designates a sliding sash, the frame of which is usually formed up of sheet metal to provide a channel 8 at the edge of the sash. The window here shown is provided with a stationary glass panel I at one end of the window frame and the sliding sash 5 slides horizontally laterally into and out of closed position, and laps the stationary panel I. The flange 3 and channel 4 of the frame are provided not only in the upper and lower rails thereof but also in the end or upright rail of the frame, and the channel 6 of the sash 5 is formed also in the upper and lower horizontal rail of the sash and upright end rail of the sash. The sash 5 is arranged with the channel 6 astride the flange 3 of the frame with one side wall or flange 8 of the channel 5 lapping'the outer side of the flange 3 with the other side wall or flange 9 of the channel 8 spaced from the flange 3 and extending into the channel 4 of the frame.

The non-absorbent weather strip means for holding the sash against undue looseness comprises a metal spring-pressed strip or shoe l0 arranged in the channel 8 of the sash 5, it being -apex portions of the springs ll.

movable with the sash and interposed between the flange 9 of the channel 6 of the sash and the inner face of the flange 3 'of the window frame. It is thrust against said flange 3 by suit able means, as springs II. The springs here shown are leaf, or bowed springs secured between their ends, as by rivets l2 to the, strip l0 and having their ends thrusting against the inner face of the flange 9 of the sash, as at l3. The portion of the flange 8 of the sash along the upright end of the sash moves into and out of lapping engagement with the portion 3 of the flange 3 of the frame at one end of the frame, and likewise the portion or strip Ill in the upright or end rail 5 of the sash moves into and out of engagement with the flange portion 3 during complete closing and partial or complete opening of the sash. The channel is preferably provided with a lining M of a non-absorbent material extending at least between the confronting surfaces of the flanges 3 and 8.

Preferably, the outer edge of the weather strip I0 is provided with an angular flange l5 at the edge of the sash forming apartial shield for the The comer at l6 between the body of the strip Ill and the flange I5 is beveled sufficiently in the portion thereof at the end edge of the sash to guide the edge of the portion 3 of the flange 3 between the strip l0 and the flange 8 when the sash 5 is being closed. The strip [0 is practically coextensive in length with the upper, lower and end rails of the sash and is spring-compressed throughout its length. In order to secure the strip III to the sash 5, one or more of the bowed springs may be secured at one end to the sash 5 or the flange 9 thereof, as by fastening members or rivets H.

The sash is provided with a suitable handle l8 which is here shown as provided with a suitable latch IQ for coacting with a keeper plate 20 on the frame I, when the sash is closed. When the sash is closed, it is sealed throughout its entire edge by the weather strip I0 being thrust by the springs H in one direction against the inner face of the flange 3 and the flange 8 being thrust in the opposite direction toward the outer face of the flange 3 by the spring II, and as there is no felt or moisture absorbent material to swell and otherwise change its condition, and render the opening and closing of the sash difficult, this sash works uniformly under all conditions.

What I claim is:

In a sliding window construction, a window frame provided with an inwardly extending sash guide flange, and a sliding sash mounted in the frame and formed with a channel at its edge arsaid channel and thrusting against the inner side ranged astride said flange with one side wall oi of said flange, whereby the en aging 01' one side the channel lapping the outer side of the flange wall of the channel and of the weather strip with and a space between the inner side of the flange the outer and inner iaces respectively of said and the other side wall 0! the channei, and a 5 flange constitutes the only guiding oi. the sash spring-pressed, non-absorbent weather strip with the frame.

located in the channel and movable with the JOHN F. ,LEVAN.
